A report on the initiatives to develop a wastewater treatment system was presented at the meeting, based on the results of interviews and researches with large cruise companies in Hạ Long on the need for a wastewater system in Tuần Châu Port.
About 502 cubic metres of wastewater was daily discharged from cruise boats into Hạ Long Bay. This wastewater was estimated to originate from different sources, including about 250 litres from each tourist staying overnight on a boat.
